Abstract:
Apparatus is provided for rotating the spray head or cap of a spray gun to manipulate a noncircular spray emitted therefrom relative to a workpiece to be coated. The apparatus includes a translator located adjacent the spray gun cap and having a drive gear meshing with a driven gear on the cap. The translator includes a twist drill and carrier block moveable longitudinally and having pins extending into helical grooves of the drill. The translator forms a noncircular passage and the block is noncircular so as to be held in the passage for longitudinal but nonrotatable movement. When the block and pins move longitudinally they cause the drill and the drive gear which is affixed thereto to rotate. A flexible, tubular plastic shaft and a flexible plastic tubular sheath extend from the translator to a remote position where a suitable drive moves the shaft longitudinally to move the block. The sheath and shaft are highly flexible and light in weight.
Abstract:
An actuator and actuator-orientator assembly orients aerosol cans in the proper position to spray a stripe of marking material. An actuator having a generally cylindrical outer surface is adapted to be mounted on the valve stem of an aerosol can and includes a spraying orifice and a pair of radially outwardly extending locating lugs. The actuator-orientator is provided with a circular central opening into which the actuator is inserted and a pair of recesses which extend radially outwardly from the central opening for receiving the locating lugs of the actuator when the actuator is properly oriented. The periphery of the central opening is defined by curved guide surfaces which extend upwardly from the recesses. A guide surface extends from each side of each recess and meets a guide surface from the other recess at the midpoint of the arc which extends between the recesses. When the actuator is inserted downwardly into the opening of the orientator and the lugs engage the guide surfaces, the actuator and aerosol can move downwardly and rotate along the guide surfaces until the lugs are seated within the recesses.
Abstract:
A nozzle monitor is disclosed. The monitor includes a hollow trunnion rotatably mounted on fluid delivery conduits. A fluid cylinder device, acting through continuous loop chain and sprocket assemblies, rotates the trunnion about a first axis. A spray nozzle assembly, including an elbow, is rotatably mounted on the trunnion and is capable of rotating in a 360* arc about a second axis which is orthogonal to the first mentioned axis. A rotary motor and transmission drives the spray nozzle assembly. The spray nozzle includes a slidable front section for varying the spray pattern of fluid issuing from the nozzle. A control system for the slidable section of the nozzle includes a fluid cylinder mounted on the trunnion, and a reciprocable element extending from the trunnion to the spray nozzle assembly along the axis of rotation of the spray nozzle assembly. The spray pattern can be controlled in any position of rotation of the spray nozzle assembly with respect to the trunnion.
Abstract:
A mobile device for repairing furnace walls includes a mobile unit on which telescopically disposed conduit means are mounted. A nozzle is mounted on the conduit means such that refractory material fed through the conduit means is discharged from the nozzle for deposit on the furnace walls. Supporting means are provided for supporting the conduit means on the mobile unit and for controlling the location and position of the nozzle whereby the conduit means may be operated from a remote position to control the location and direction of discharge of refractory material from the nozzle and provide for depositing the refractory material on the furnace wall with a minimum of waste.
Abstract:
Liquid is distributed at a substantially desired uniform rate per unit area on a surface having a dimension which varies in a predetermined manner by projecting at the surface a divergent stream of the liquid from a nozzle which can be moved towards and away from the surface, the rate of supply of liquid to the nozzle being substantially proportional to the distance between the nozzle and the surface. The invention is useful in applying a wear-resisting liquid coating to the rolls of hot metal rolling stand, the chosen rate of discharge being sufficient to mitigate wear of the work rolls without derogating from their performance.
Abstract:
A painting robot system includes a robot and a spray gun unit. The robot includes a plurality of robot arms and a drive shaft member disposed on a distal end robot arm of the multiple robot arms, the drive shaft member being rotatable about a distal end drive axis. The spray gun unit is mounted on the robot arm. The spray gun unit includes a support member fixed to the distal end robot arm, guide members disposed on the support member, a plurality of spray guns disposed on the support member, and a linkage mechanism connecting between the movable spray guns and the drive shaft member. A spacing between at least one pair of adjacent spray guns can be varied via the linkage mechanism by rotating the drive shaft member of the robot.
Abstract:
A nozzle, comprises an elongated hollow lance configured for feeding a coating agent through the lance along a longitudinal axis of the lance and at least one nozzle opening configured for dispensing the coating agent. The nozzle opening is arranged in a lateral surface of the lance and dispenses the coating agent sideways with respect to the longitudinal axis of the lance. The nozzle opening is rotatable about the longitudinal axis of the lance such that the coating agent can be dispensed in differenct directions according to an angular position of the nozzle opening.
Abstract:
A sprayer apparatus for dispensing liquid fertilizer, weed control or liquid insecticide from an elongated storage tube using one hand. A see-through plastic storage tube has a spray nozzle one end and a handgrip with trigger on the opposite end. Compressing the trigger moves a trigger rod to move a piston that forces gravity fed liquid through the spray nozzle. The spray nozzle can be located in a housing having a convex curved outer surface along with a wheel protruding from the bottom surface of the housing. The wheel can have conical side edges and a flat exterior side. Alternatively, the wheel can have rounded outer edges. Visible markings on the exterior of the plastic storage tube can tell the user the remaining amount of the liquid stored inside. An optional protruding handgrip can be located halfway down the storage tube for allowing the device to be controlled by two hands. A second version includes a two way valve located inside the storage tube. The valve connects the spray nozzle to either the interior of the storage tube or to an interior siphon tube that has an opening located inside the handgrip. The two way valve allows the device to gravity feed liquid to the spray nozzle when the spray nozzle is located adjacent to the ground. The second position of the valve allows the device to suction liquid from inside the handgrip when the spray nozzle is oriented above the the handgrip.
Abstract:
A system for applying moisture to a food product in a display case. The system has a mist bar adjustably mounted on brackets to adjust the direction of the mist. Mist tips are mounted to the mist bar at determined intervals and are individually controlled to an open or closed position. The system has a controller that controls the cycle time of the mist application. The mist tips produce a fine fog like mist that settles on the food product. The mist tips are provided with a ball check that acts as a seal and prevents dripping.
